Abstract:

Goupitan Power Plant which is run by Wujiang Hydropower Development Company Limited. has experienced a high faulty rate on oil pressure equipment of speed regulation system after starting up.Because of multiple leakages, oil pump vibration, abnormal loading/unloading condition of oil pump and unreasonable operation mode of oil pump, it cannot meet the requirement of economic operation. According to the situation above, improvement is made from the equipment sealing transformation and control procedure optimization. It greatly improves the economic efficiency of the oil pressure device, and completely avoids the leakage caused by the defect of equipment, which has certain promotion value.
